2010.5 Citroen DS4 warning

Safety
Seat belt unfastened warning lamp
This warning lamp comes on in the instrument panel when one or more rear passengers unfasten their seat belt. From approximately 12 mph (20 km/h), this warning lamp flashes for two minutes accompanied by an audible signal of increasing volume. Once these two minutes have elapsed, this warning lamp remains on until the one or
more rear passengers fasten their seat belt.
Seat belt unfastened warning lamps display
3. Rear right seat belt warning lamp. 4. Rear centre seat belt warning lamp. 5. Rear left seat belt warning lamp. When the ignition is switched on, with the engine running or when the vehicle is moving at less than 12 mph (20 km/h), the corresponding warning
lamps 3 , 4 and 45 come on in red for approximately 30 seconds, if the seat belt is not fastened. When the vehicle is moving at more than 12 mph
(20 km/h), the corresponding warning lamps 3 , 4 and 5 come on in red, accompanied by an audible signal and a message in the screen, if a rear passenger has unfastened their seat belt.

The driver must ensure that passengers use the seat belts correctly and that they are all restrained securely before setting off. Wherever you are seated in the vehicle, always fasten your seat belt, even for shor t journeys. Do not interchange the seat belt buckles as they will not fulfil their role fully. The seat belts are fitted with an iner tia reel permitting automatic adjustment of the length of the strap to your size. The seat belt is stowed automatically when not in use. Before and after use, ensure that the seat belt is reeled in correctly. The lower par t of the strap must be positioned as low as possible on the pelvis. The upper par t must be positioned in the hollow of the shoulder. The iner tia reels are fitted with an automatic locking device which comes into operation in
the event of a collision, emergency braking or if the vehicle rolls over. You can release the device by pulling firmly on the strap and
releasing it so that it reels in slightly.
In order to be effective, a seat belt must: - be tightened as close to the body as possible, - be pulled in front of you with a smooth movement, checking that it does not twist, - be used to restrain only one person, - not bear any trace of cuts or fraying, - not be conver ted or modified to avoid affecting its per formance. In accordance with current safety regulations, for all repairs on your vehicle, go to a qualified workshop with the skills and equipment needed, which a CITROËN dealer is able to provide. Have your seat belts checked regularly by a CITROËN dealer or a qualified workshop, par ticularly if the straps show signs of damage. Clean the seat belt straps with soapy water or
a textile cleaning product, sold by CITROËN dealers. After folding or moving a seat or rear bench seat, ensure that the seat belt is positioned and reeled in correctly.
Recommendations for children
Use a suitable child seat if the passenger is less than 12 years old or shor ter than one and a half metres. Never use the same seat belt to secure more than one person. Never allow a child to travel on your lap.
In the event of an impact
Depending on the nature and seriousness of the impact , the pretensioning device may be deployed before and independently of the airbags. Deployment of the pretensioners is accompanied by a slight discharge of harmless smoke and a noise, due to the activation of the pyrotechnic car tridge incorporated in the system. In all cases, the airbag warning lamp comes on. Following an impact, have the seat belts system checked, and if necessary replaced, by a CITROËN dealer or a qualified workshop.

Deactivation
Only the passenger's front airbag can be deactivated:  with the ignition off , inser t the key in the n offpassenger airbag deactivation switch,  turn it to the "OFF" position,  then, remove the key keeping the switch in the new position.
According to version, this warning lamp comes on either in the instrument panel or in the seat belt and passenger's front airbag warning lamps display when the ignition is on and until the airbag is reactivated.
To assure the safety of your child, the passenger's front airbag must be deactivated when you install a "rear facing" child seat on the front
passenger seat. Other wise, the child would risk being seriously injured or killed if the airbag were deployed.
Reactivation
When you remove the child seat, turn the switch to the "ON" position to reactivate the airbag and so assure the safety of your front passenger in the event of an impact.
With the ignition on, this warning
lamp comes on in the seat belt and passenger's front airbag warning lamps display for approximately one minute, if the passenger's front airbag is activated.
Operating fault
If this warning lamp flashes, contact a CITROËN dealer or a qualified workshop. The passenger’s front airbag may no longer be deployed in the event of a serious impact.
If even one of the two airbag warning
lamps comes on continuously, do not install a child seat on the front passenger seat. Have the system checked by a CITROËN dealer or a qualified workshop.
If this warning lamp comes on in the instrument panel, accompanied by an audible warning and a message in the screen, contact a CITROËN dealer or a qualified workshop to have the system checked. The airbags may no longer be deployed in the event of a serious impact.

Curtain airbags
System which protects the driver and passengers (with the exception of the rear centre passenger) in the event of a serious side impact in order to limit the risk of injury to the side of the head. Each cur tain airbag is built into the pillars and the upper passenger compar tment area.
Deployment
The cur tain airbag is deployed at the same time as the corresponding lateral airbag in the event of a serious side impact applied to all or par t of the side impact zone B , perpendicular to the longitudinal centreline of the vehicle on a horizontal plane and directed from the outside towards the inside of the vehicle. The cur tain airbag inflates between the front or rear occupant of the vehicle and the windows.
Operating fault
In the event of a minor impact or bump on the side of the vehicle or if the vehicle rolls over, the airbag may not be deployed. In the event of a rear or front collision, the airbag is not deployed.
If this warning lamp comes on in the instrument panel, accompanied by an audible signal and a message in the screen, contact a CITROËN dealer or a qualified workshop to have the system checked.
The airbags may no longer be deployed in the event of a serious impact.

Electric parking brake
The electric parking brake combines2 operational modes: - Automatic Application/Release Application is automatic when the engine stops, release is automatic on use of the accelerator (activated by default), - Manual Application/Release The parking brake can be applied/released manually by pulling control lever A .
Do not place any object (packet of cigarettes, telephone...) between the gear lever and the electric parking brake control lever.
It is recommended that you do not apply the parking brake in very cold conditions (ice) and during towing (breakdown, caravan...). Deactivate the automatic functions and release the parking brake manually.
If this warning lamp comes on in the instrument panel, the automatic mode is deactivated.
Programming the mode
Depending on the country of sale of the vehicle,
the automatic application when the engine is switched off and the automatic release when you press the accelerator can be deactivated.
Activation/deactivation is done using the vehicle configuration menu; refer to the section covering the configuration of your vehicle's systems.

In the case of towing, a loaded vehicle or parking on a gradient, make a maximum application of the parking brake then turn the front wheels towards the pavement and engage a gear when you park. After a maximum application, the release time will be longer.

With the vehicle stationary, the parking brake is automatically applied when the engine is switched off.
